The fixed component 6 is movably arranged on the lower platform 33, the fixed component 6 comprises a left positioning plate and a right positioning plate, and the distance between the two positioning plates can be adjusted or locked. When the assembled reactor is placed on the lower platform 33, the distance between the two positioning plates is adjusted, then locking is carried out, and the reactor is firmly fixed in the working area of the reactor metal shell crimping machine. The fixing member 6 is used for protecting the reactor when the metal case is crimped.

Specifically, the shaping assembly comprises a first shaping assembly 4 and a second shaping assembly 5, wherein the number of the first shaping assembly 4 is two, and the two first shaping assemblies are respectively fixed on the left supporting column 32 and the right supporting column 32. The lower platform 33 is provided with a heightening plate, and the second shaping assembly 5 is fixedly arranged on the heightening plate.

In particular, fig. 3 shows a schematic structural diagram of the first shaping assembly. As shown in fig. 3, the first reforming assembly 4 includes a cylinder 41, a fixing plate 42, a connecting plate 43, and a reforming part 44. The cylinder 41 is fixed on the supporting column 32 through a fixing plate 42, and preferably, the cylinder 41 is movably connected with the supporting column 32, so that the first shaping assembly can move up and down on the supporting column 32 to meet the shaping and crimping requirements of different reactors. The output shaft of the cylinder 41 is connected to the shaping portion 44 through the connecting plate 43. Further, the lower plane of the end of the two shaping parts 44 of the first shaping assembly 4 close to each other is provided with a certain inclination. When the first shaping assembly 4 works, the output shaft of the cylinder 41 contracts, the shaping parts 44 are driven by the connecting plate 43 to move oppositely, so that four clamping jaws are bent, the lower planes of the two shaping parts 44 close to the proximal ends are provided with a certain inclination, the bending angles of the four clamping jaws can be controlled under the matching of the output shaft of the cylinder 41, and the contact surface between the clamping jaws and the shaping parts 44 can be larger due to the certain inclination, so that the clamping jaws are prevented from being broken by the shaping parts 44. Preferably, when the shaping portion 44 is made of a non-rigid material, a slide rail 45 is arranged below the shaping portion 44, one end of the slide rail 45 is fixed on the support column 32, the shaping portion 44 slides above the slide rail 45, and the slide rail 45 provides guidance for the shaping portion 44, so that the consistent bending effect of the shaping portion 44 on the jaws in each contact is ensured.

In particular, fig. 4 shows a cross-sectional view of the second fairing component 5. As shown in fig. 4, the second truing assembly 5 includes a slide cylinder 51, a connecting plate 52, a spring positioning pin 53, and a movable plate 54. A through hole is formed in the connecting plate 52, the spring positioning bolt 53 penetrates through the through hole to connect the movable plate 54 with the connecting plate 52, and the other end of the connecting plate 52 is connected with the output end of the sliding table cylinder 51. The movable plate 52 can be driven to move on a straight line by the sliding table cylinder 51. When the slide table cylinder 51 is extended, fig. 5 shows the positional relationship between the second truing assembly 5 and the push-down cylinder 2 and the protection assembly 7. As shown in fig. 5, a yielding circular hole is formed in the connecting plate 52 of the second shaping assembly 5, and the output shaft of the downward pressing cylinder 2 passes through the movable plate 54. The movable plate 54 is located right above the protection component 7. When the second shaping assembly 5 works, the sliding table cylinder 51 extends out to drive the movable plate 54 to move right above the protection assembly 7, that is, the movable plate 54 is just above the reactor. The output end of the downward pressing cylinder 2 penetrates through the abdicating round hole, the movable plate 54 is vertically pressed downward, the size of the movable plate 54 is matched with the size of the upper surface of the reactor, and the movable plate 54 downwards presses four clamping jaws which are bent by the first shaping assembly, so that the final shaping and crimping work is completed. After the final shaping and crimping process is completed, the output end of the pressing cylinder 2 retracts, the movable plate 54 loses downward pressure, and moves vertically upwards under the action of the spring positioning pin to wait for the next work. Figure 7 shows a schematic view of the finally crimped reactor metal case, as shown in figure 7, with the four jaws completely flattened so that the E-and I-pieces are accurately fixed in the desired position and do not move. On the other hand, because the whole movable plate 54 is vertically pressed downwards, the extrusion force between each part of the E piece and the I piece is consistent, the thickness of the colloid between the E piece and the I piece can be controlled by controlling the pressing degree of the movable plate 54, the movable plate 54 is pressed downwards to extrude redundant colloid, the reactor with stable performance is obtained, the qualification rate is high, and the condition of rework rarely occurs.

Fig. 6 shows a connection diagram of the protection component 7 and the reactor. Illustratively, as shown in fig. 6, the protection assembly 7 includes a left protection member 71, a right protection member 72, and a fastening screw 73. Two through holes are formed in the side surface of the left protection piece 71, and two threaded holes are formed in the corresponding position of one side of the right protection piece 72. The fastening screw 73 is connected to the right protector 72 after passing through the through hole of the left protector 71. It is sufficient to adjust the positions of the left and

right protectors

71, 72 so that the upper surface of the protection assembly 7 is flush with the surface of the reactor metal cover, and then rotate the fastening screw 73 so that the left and

right protectors

71, 72 abut against the metal case of the reactor. The protection component 7 is used for preventing the surface of the metal shell of the reactor from deforming when the first shaping component 4 presses the claws, so that the reactor is unqualified. Preferably, the left protector 71 and the right protector 72 are made of aluminum strips.

Further, the present invention also includes an electrical control assembly, which illustratively includes a programmable logic controller, a photoelectric inductive switch 11, a solenoid valve, and a dc power supply. As shown in fig. 8, the photo-electric induction switch 11 is mounted on the lower stage 33 to identify whether a work area prevents a reactor.

The plurality of electromagnetic valves are respectively and electrically connected with the cylinder 41 in the first shaping assembly 4, the sliding table cylinder 51 in the second shaping assembly 5 and the pressing cylinder 2, and the operation of the electromagnetic valves is controlled. The editable logic controller is connected with the electromagnetic valves and provides control logic for the electromagnetic valves. The direct current power supply supplies power to the whole device.

The specific working process of the invention is as follows: the assembled reactor is first protected with the protection component 7. Specifically, the protection assembly 7 is installed by placing the left protection member 71 and the right protection member 72 against the metal shell of the reactor, fixing the left protection member 71 and the right protection member 72 by the fastening screw 73, and finally making the upper surface of the protection assembly 7 flush with the surface of the metal cover plate of the reactor. Then, the reactor which is well protected is placed in a working area on the lower platform 33, the left positioning plate and the right positioning plate of the fixing assembly 6 are close to the middle, the reactor is fixed, and the position of the reactor is corrected to ensure that the reactor is in the working area. And after recognizing that the reactor is placed in the working area, the photoelectric inductive switch 11 sends a signal to the programmable logic controller. The programmable logic controller controls the first shaping component 4 to start working through a solenoid valve. Specifically, the cylinders 41 in the two first shaping assemblies 4 start to contract to drive the shaping portions 44 to approach each other, four jaws of the reactor are bent by extrusion, and after the operation is completed, the shaping portions 44 are away from each other. The programmable logic controller controls the second shaping component and the pressing cylinder 2 to start working through a solenoid valve. Specifically, slip table cylinder 51 extends, drives activity board 54 moves directly over the reactor, the output that pushes down cylinder 2 stretches out, passes the round hole of stepping down of connecting plate 52, supports activity board 54 downstream. The movable plate 54 flattens the four claws, and due to the high force, a part of glue between the E piece and the I piece can be extruded out, so that the thickness of the glue layer is consistent, and the thickness of the glue layer can be controlled by controlling the extending length of the output end of the downward pressing cylinder 2. Exemplarily, after 5S, the push-down cylinder 2 is retracted, and the movable plate 54 rebounds out of the reactor by the spring positioning 53. And the sliding table cylinder 51 retracts to finish the shaping and crimping work of the reactor.
